How FU1 - Renting a co-location space/rack with 1 kW of power - works
Introduction
DCFootprint estimates the environmental impacts of the life cycle of the Datacenter, depending on its generic description (based on the input parameters), before computing the share of impact of each other Functional Unit.
This Functional Unit “1” is defined in the Ademe Cloud & Datacenter PCR, as “Provide hosting services for operation of the IT equipment”.
Version 1 - early stage version
This is the very first version of the methodology. It will evolve in the future, in order to be able to compare results between each model version. Please see the roadmap page.
To discuss about this methodology and how it should evolve, please look for an existing thread or open a new one, on community.dcfootprint.org.

Methodology
FU1Impacts(1 kW, 1 Year) = DatacenterImpacts / CommercializedPower / DatacenterLifetime
With:
DatacenterImpacts: the impacts calculated before in the Datacenter section, see the FU0 methodology.
DatacenterLifetime: the lifetime set as an input.
CommercializedPower: the total power that the provider car sell to its clients, in kW. Formula is:
CommercializedPower = TotalPowerInstalled / PowerUsageEffectiveness
Version 2
Planned for 2026.
